Description

[Detailed Description of the Invention] The present invention relates to a construction panel useful for forming the outer walls of buildings and structures by a dry method.

Recent energy saving measures in architecture have mainly focused on insulation structures.

One of the main structures is one constructed with metal siding materials.

In particular, among metal siding materials, those that use polyurethane foam or other plastic foam as the core material vary depending on the distribution density of the foam, the directionality of the bubbles, the material and shape of the front and back materials, and the fixing structure of both surfaces. The decorative surface of metal siding material changes to a concave or convex shape.

Possible causes of this are the physical properties, shape, and mounting structure of the backing material.

In addition, as a core material, the amount of raw material used is minimal, it foams effectively, there are no areas where the foam is not present where the backing material and the foam are bonded, and the bonding between the fronting material and the backing material is ensured. It is desirable that only the required amount be supplied to the bonding section.

Furthermore, the heat insulating structure must not only be airtight, but must also be designed to prevent condensation caused by the relative relationship between temperature and humidity.

As a countermeasure against this, appropriate ventilation is generally required.

However, conventional building materials of this type have been lacking in this respect.

Furthermore, condensation not only corrodes the rim and other parts, but also causes mold.

This invention was devised in view of these points,
Mainly: ■ Preventing dew condensation by forming ventilation channels after construction, and preventing mold growth using anti-mold agents.
Features include reliable adhesion of the edge of the backing material to the surface material, ■reducing the amount of core material, ■strengthening mechanical strength, ■improving sound absorption, and ■adding cushioning properties to the contact surface with the body rim, etc. We propose architectural panels.

The architectural panel according to the present invention will be explained in detail below using the drawings.

FIG. 1 is a perspective view showing an example of the above-mentioned panel. The main body 1 has a rectangular decorative surface 1a, and is made of a moldable plate such as a thin metal plate or a synthetic resin plate.

Reference numerals 2 and 3 denote side walls, which are formed by bending both ends of the main body 1 vertically or at an angle (not shown), and the edges of the side walls 2 protrude outward to form a male connecting portion 4.

The male connecting portion 4 consists of an insertion edge 5 and a tongue piece 6 whose tip is bent as shown in the figure or to the opposite side (not shown).

Reference numeral 7 denotes a female connecting portion, which has an insertion groove 8 formed by bending the end edge of the side wall 3 inward in a U-shape, and an extension portion 10 extending the lower edge 9 further outward; It consists of a protrusion 11 provided parallel to the side wall 3, and a tongue piece 12 with the tip of the extension part 10 bent outward.

Note that the protrusion 11 is provided as necessary, and can also be made to protrude in the opposite direction to that shown in the figure.

In particular, the protrusion 11 has the function of airtightness and draining when the male and female molds are connected.

13 is a synthetic resin foam (hereinafter simply referred to as foam) that is filled in the gutter-like part formed by the main body 1 and the side walls 2 and 3, and is mainly filled with a heat insulating material, an adhesive, a lightweight raising material, Functions as a cushioning material, sound absorbing material and non-moisture absorbing layer.

The materials include polyurethane foam, polyisocyanurate foam, phenol foam, vinyl chloride foam, polyimide foam, polyethylene foam, and polyamide foam, and foams are mainly produced from raw materials.

14 is a waterproof sheet, and a plurality of recesses 15 are formed in parallel with the longitudinal direction of the sheet at appropriate intervals P to improve the strength of the waist panel itself and to prevent the generation of voids on the top surface in the foaming direction when forming a synthetic resin foam, and to improve the effectiveness of the raw material. This is aimed at improving the foaming ratio.

Further, the recesses 15a existing in the portions close to the side walls 2 and 3 push out the raw material to the front and back material bonding parts 16, and reliably supply the raw material to the bonding part by suppressing the amount of raw material passing through by so-called squeezing. It is.

Furthermore, one surface of the waterproof sheet 14, especially the surface that does not come into contact with the foam, the surface where the so-called recesses 15 are exposed, is coated with a moldproofing agent 1.
4b was applied.

In addition, the cross section of the recesses 15, 15a is shown in FIG.
- Form as shown in c.

Note that, for example, W1=3 to 8rrgIL1h=1 to 101
It is possible to set rrIn1d=3 to 5 mmφ and W2=5 to 10 wrL.

The waterproof sheet 14 is made of a laminated material of one or more of gypsum paper, asbestos paper, kraft paper, synthetic resin film, metal foil, and nonwoven fabric.

The antifungal agent 14b is made of, for example, one of metal soap, phenylacetic acid, mercury, phenol compounds, aniline derivatives, benzimidazole derivatives, sulfur compounds, and sanicil anilide.

A sheet with a membrane formed thereon, a flocked sheet, etc. are used.

Next, examples will be described.

Assume that the panel shown in FIG. 1 is manufactured using the apparatus shown in FIG. 3.

In the figure, A is a heating type mold consisting of an upper and lower mold that rotates in the direction of the arrow, B is a waterproof sheet molding machine, C is a molding machine for the main body 1, and D is a synthetic resin foam discharging machine.

Therefore, the main body 1 is a 0.2777F color iron plate,
The synthetic resin raw material is polyurethane resin (Daiichi Kogyo Seiyaku's M system), and the waterproof sheet 14 is kraft paper (1
909/d) laminated with polyurethane resin, the surface of which was coated with metal soap at 209/lri, the recess 15 is the cross section of Fig. 2a, P = 10 books, Wt = 4
mmXh = 3 rrrm.

For example, assume that the mold A rotates at a speed of 30 m/min, the mold temperature is set at 600 C, and the raw material is discharged onto the back surface 1b of the molded main body 1 in a somewhat average manner.

During the cream time or gel time period,
Preferably, at the end of the gel time, the waterproof sheet 14 comes into contact with the raw material as shown in FIG. 1, is supplied to the mold A, is cured in the mold A, and is continuously sent out from the outlet as the panel shown in FIG.

In particular, at this time, the back surface 14a of the waterproof sheet 14 is transported to the entrance of the mold A without bending, so the chemical reaction of the raw materials and the height of foaming are not suppressed, and at the end of the process, it comes into contact with the foaming top surface, resulting in effective foaming. At the same time, the raw material for the side wall portion is supplied to the back surface of the connecting portion of the main body 1 and the back end portion of the waterproof sheet 14 by the aforementioned extrusion action to ensure adhesion.

Therefore, architectural panels will be much stronger panels than before, since the strength of the backing material of the sandwich structure directly affects the mechanical strength of the panels themselves.

Therefore, when we cut the manufactured building panel and observed its cross section, we found that the synthetic resin foam 13 had a homogeneous foam structure (closed cells), and its density was the same as that obtained by slightly compressing the top surface of free foam. Ta.

Further, the synthetic resin foam 13 and the back surface 14a of the main back surface 1b1 waterproof sheet were bonded together, and the bonding of both surfaces was secure, with no peeling observed at all.

In addition, as shown in FIG.
When installed on the top, it will surely form the ventilation path 18 and prevent condensation and
And no mold growth was observed, main body 1, waterproof sheet 1
4. The furring rim 17 was not corroded or contaminated.

What has been described above is only one embodiment of the construction panel according to the present invention, and a flame retardant and inorganic porous particles can also be added to the synthetic resin foam.

Furthermore, as shown in FIG. 5, a synthetic resin foam 13 and a waterproof sheet 14 can also be formed.

As mentioned above, according to the architectural panel according to the present invention,
It has the characteristics of sufficiently exhibiting the effects of (1) to (4) described above, and has the advantage of being easy to manufacture and being manufactured at low cost.
